ABSTRACT:
A dual blade fountain coater for simultaneously coating the opposite sides of a moving web of paper includes a pair of oppositely positioned, non-contacting fountains and a pair of oppositely positioned metering blade assemblies which are mounted for movement about a common transverse pivot axis, which pivot axis is substantially coincidental with the blade contacting region on the web. Each assembly is independently adjustable of the other for adjusting blade angle and each fountain is similarly independently adjustable for varying the coating contacting region and dwell time. Metering bars may be mounted on the blades.
